Adding probiotic strains modulates intestinal mucin secretion in growing pigs ileum

摘要

Mucin represents the most important barrier of the gastrointestinal tract against pathogens that generate enteric diseases. Therefore, arises the need to implement nutritional strategies that promote intestinal mucin production and health, and in turn, the decline in the use of antibiotics to mitigate the diseases of this stage comes. Therefore, the effect of adding different probiotic strains (Lactobacillus casei, Lactobacillus acidophilus and Enterococcus faecium) on the production of Sulfated Acid Mucins (MAS), Non- Sulfated Acid Mucins (MANS) and Neutral Mucins (MN) in newly weaned piglets was assessed. 35 days 1 piglets (21 days old), 15 and 30 weaned humane euthanasia was performed, and were extracted the ileum to evaluate the production of intestinal mucins different. They were offered the animals a commercial diet with added antibiotics and one without addition of antibiotic; and different probiotics are added in the drinking water. The experimental design was randomized block in split plot arrangement. A significant increase (P 0.01) in the production of MAS, MN MANS and on day 30 after weaning in those animals fed E. faecium, compared to those who ate the diet with added antibiotics was observed. E. faecium in the diet of weaned piglets promotes the production and secretion of mucin, which could be reflected in the intestinal health of themselves and their time, clinical, health and productive parameters of the animals.
